Narrative:

On the takeoff roll at around 100 knots the airplane began leaning to the right and began to sound and feel as though a tire had just blown out. It took 2-4 seconds before both the ca and I realized what probably happened and as I was searching for the words to describe what I thought had happened; the ca was obviously thinking the same and called abort ; abort. The ca put in full reverse thrust and we both applied full breaking and brought the airplane to a full stop 500 ft short of the end of runway. The pb was set where we stopped and we began to assess the situation. We informed the tower of the abort and our intent to stay put until we knew more about the situation; asked the passengers to remain seated; and discussed the situation with the flight attendant. We determined there was no immediate danger that would require an emergency evacuation and began discussions with the local operations and our companies mx control. We concluded that the airplane should be deplaned where we where and then towed in to the ramp. Within 30 minutes of the beginning of the takeoff run; all the passengers had been deplaned and bussed back to the terminal. We then began discussions with mx control about towing the airplane back to the ramp after we had now determined that we had blown both right main tires and put a hole through the flap. Mx approved the tow and as we proceeded we got a landing warning on the right main that it was not fully down and locked and so we quickly stopped the tow having moved only about 40ft. It was then discovered that the right main gear down-lock arm had been broken off the aircraft frame and was no longer holding the main gear in the down locked position.

The CA put in full reverse thrust and we both applied full breaking and brought the airplane to a full stop 500 ft short of the end of RWY. The PB was set where we stopped and we began to assess the situation. We informed the tower of the abort and our intent to stay put until we knew more about the situation; asked the passengers to remain seated; and discussed the situation with the FA. We determined there was no immediate danger that would require an emergency evacuation and began discussions with the local operations and our companies MX control. We concluded that the airplane should be deplaned where we where and then towed in to the ramp.
